Sheet with weight

ABSTRACT

A sheet with weight preventing the leakage of rainwater with easy operation. The sheet with weight comprises a sheet portion and a weight mounted along an edge of said sheet portion. The sheet may be accommodated in a cylindrical portion integrally formed along the edge of the sheet portion, and the weight can be a metal chain.

BACKGROUND OF THE INVENTION

[0003] The present invention relates to a sheet with weight, and moreparticularly to a sheet with weight preferably used for a roof of ahouse broken by an earthquake or the like.

[0004] In case that a roof of a house is broken due to an earthquake orthe like, the broken portion is usually covered by a plastic sheet orthe like to prevent the leakage of rainwater. Since merely covering thebroken portion by the sheet allows the sheet to be blown away due towind, sand bags or the like are put on the sheet.

[0005] With the above-mentioned conventional method, however, theportions without sand bags blow hard in wind, and rainwater enters fromthese portions into the house. In order to prevent leakage, it ispossible to stick the sheet fast to the surface of the roof without agap utilizing string, adhesive tape and so on. But, in this case,scaffolding or the like is necessary, and it takes a long time to coverthe broken portion with the sheet.

BRIEF SUMMARY OF THE INVENTION

[0006] It is therefore the object of the present invention to provide asheet with weight to prevent the leakage of rainwater or the like witheasy operation.

[0007] To accomplish the above objective, the sheet with weightaccording to the present invention comprises: a sheet portion; and aweight mounted along an edge of said sheet portion. With the above sheetwith weight, only transporting the sheet to the place where the sheet isused and spreading it at the place allows the overall or partial edge ofthe sheet to be stuck fast to the place, which prevents the leakage ofrainwater or the like.

[0008] In the sheet described above, the weight can be accommodated in acylindrical portion integrally formed of the edge of the sheet portion.It is very convenient to form the weight so as to be replaceable fromthe cylindrical portion.

[0009] In the sheet described above, the weight can be produced by ametal chain, which makes it possible to construct the sheet usingordinarily used metal.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be more apparent from the ensuingdescription with reference to the accompanying drawings wherein:

[0011]FIGS. 1A and 1B are a partially sectional plan view and asectional view observed from the line A-A; and

[0012]FIG. 2 is a schematic perspective view showing a usage of thesheet with weight illustrated in FIGS. 1A and 1B.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Now, a preferred embodiment of the present invention will beexplained with reference to the drawings.

[0014]FIGS. 1A and 1B show a sheet with a weight (hereinafter referredto as the “sheet”) according to one embodiment of the present invention.The sheet 1 comprises: a sheet portion 2 made from resin; cylindricalportions 3 at upper and lower, right and left edges of the sheet portion2; a metal chain 4 accommodated in the cylindrical portions 3.

[0015] The sheet portion 2 has the shape of a rectangle, and ispreferably made from resin. It is possible to make the sheet portion 2of waterproof cloth. The sheet portion 2 is preferably foldable fortransportation.

[0016] The cylindrical portions 3 are formed to easily accommodate themetal chain 4 and eliminate the gap between the edges of the sheetportion 2 and the roof where the sheet 1 is put. Besides cylindricalshapes, other shapes will do as long as the metal chain 4 isaccommodated at the overall edge of the sheet portion 2. The metal chain4 can partially be exposed.

[0017] The reason why the metal chain 4 is used as a weight is that itis convenient for transportation and storage with the sheet 1 beingfolded. But, it is possible to use short metal rods or the like if it iseasy to fold the sheet portion 2. Cylindrical plastic capsules withwater therein may also be used as a weight.

[0018]FIG. 2 shows a usage of the sheet 1 with the above-mentionedconstruction to prevent the leakage of rainwater by covering a brokenportion 5 of a roof of a house. With this sheet 1, only transporting thesheet 1 to a roof and spreading the sheet 1 to cover the broken portion5 allows the overall edge of the sheet 1 to be stuck fast to the surfaceof the roof, which prevents the leakage of rainwater.

[0019] If the metal chain 4, illustrated in FIG. 1 of sheet 1, is tooheavy, it is not easy to carry the sheet 1 to the roof. The weight ofthe metal chain 4 of the sheet 1 is preferably selected such that thesheet 1 may be easily carried and, when adjusted so that the sheet 1covers the broken portion 5, the edges are not lifted by wind.

[0020] Although the metal chain 4 is accommodated at the overall edge toeliminated the gap between the overall edge of the sheet portion 2 andthe surface of the roof in the above embodiment, it is possible topartially mount the metal chain 4 to the edge of the sheet portion 2 topartially stick the sheet portion 2 fast to the surface of the roof.
